Anyone using a Gear Venders O/D unit?

Old Man Ray: If you happen to have a moment, could you elaborate on what all you had to do with modifying the tunnel? I'm not overly experienced with doing these things so if I'm going to have to cut things out, I might have to re-think buying one of these units. What car did you add your OD unit to? The car I'm thinking about putting it into is a 74 Duster (225). Many thanks to you!!!

Installed it in a Pontiac not a duster. Supershafts may be able to help better to answer your specific install since he has done several in different vechicals. In my case I had to cut out about a five inch length of the tunnel and raise it about two inches to clear the OD unit. Not trying to scare you away from the idea. It was well worth it to me. Hope that helps.
